Join this Genetics, Development, and Cell Biology Promising Scientist Research Series to hear Dr. Atiako Kwame Acheampong, Postdoctoral fellow in the Kiever lab at the University of North Carolina - Chapel Hill, discuss the intricate interplay between cellular systems such as phytohormone, cytokinin, and protein degradation mechanisms of autophagy to activate organ-specific responses to ever-changing environmental stimuli or physiological cues.

Synopsis: How organisms reprogram cellular systems in response to rapid changes in internal and external cues is central to growth and development. Plants are sessile organisms that require intricate interplay between cellular systems such as phytohormone, cytokinin, and protein degradation mechanism of autophagy, to activate organ-specific responses to ever-changing environmental stimuli or physiological cues (Fig. 1). I explored the molecular mechanism underlying the interaction between cytokinin and autophagy in root development. Findings from my research show that cytokinin-dependent responses of Arabidopsis roots proceed via a novel pathway that involves the post-translational autophagic regulation of cytokinin signaling components. In a parallel research, using a combination of omics assays in rice, I show that cytokinin regulates transcriptional changes in root-expressed genes by altering the chromatin landscape near these genes.
